Anybody have a write-up for changing the front pinion seal? Mine's leaking a little and I figured I'd go ahead and replace it when I change my front driveshaft and yoke. I assume removing the flange/yoke is the hard part, but I thought anybody who's done it before might have a tip or 2.

 

anybody?

 

2K1TJ - Mine was leaking a little and I took it to the Dealer to have it fixed under warrantee.

 

Thanks. I figured that's about all there was to it. I already have the front shaft out waiting to install my JE Reel, so I guess I'm half way there.


I've had it regeared, so I figured they wouldn't warranty the seal. That's why I didn't take it to the dealer. I hate dealing w/ them anyway unless it's absolutely necessary

 

2K1TJ - I agree with you, but wanted to see if/how the warrantee works. I brought it there to have it fixed, but it turns out that by the time I got around to binging it to them it had stopped leaking. They put it on the lift and didn’t see the leak. They called me out and I showed them where it had been leaking, but it looked like it stopped. They offered to pull the driveshaft and look at the pinion nut. When they took the driveshaft off there was some small amount of surface oil inside the flange. They said sometimes oil from the assembly can leak out, and they thought that was the case with my seal. They did offer to take the nut off and continue working on it, but I told them to just bolt the driveshaft back on and I would watch it. The tech said the warrantee usually covers the seal if is dripping, not just “moist”, but if I ever wanted to have it replaced I could bring it back and they would fix it under warrantee.

When you install the new seal I believe there is a range of recommended torque setting for the pinion nut (160-200 ft. lbs.) depending on the torque required to turn the nut before removal.
